SPECIFICATION forming part -of lLetters v:Patent No. 633,334, datedSeptember 19, 1899;

Y Application filed ,Tune 9, 1399. Serial No:l 719,945. (No modell) Toall whom, t may concern.-

Be it known that I, WILLIAM LUTHER Bo- GLE, a citizen of the UnitedStates, residing at Columbus, in the county of Lowndes and State ofMississippi, have invented a new and useful Clevis, of which thefollowingis a speciication.

The invention relates to improvements in clevises.

The object of the present invention is to improve the construction ofplow-clevises and to provide a simple, inexpensive, and eiiicient onewhich will be capable oi' ready adjustment to vary the depth of a plowand in which the pivot-bolt will be locked against accidentaldisplacement.

The invention consists in the construction and novel combination andarrangement of parts hereinafter fully described, illustrated in theaccompanying drawings, and pointed out in the claims hereto appended..

In the drawings, Figure l is a perspective view of a plow-clevisconstructed in accordance with this invention and shown applied to aplow. Fig. 2 is a transverse sectional view taken longitudinally of theclevis. Fig. 3 is a detail perspective view of the clevis. Fig. 4 is asimilar view of the removable pin.

Like numerals of reference design ate corresponding parts in all thefigures of the drawings.

1 designates a plow-beam having its front end 2 inclined upward, asclearly illustrated in Fig. l of the accompanying drawings, and providedadjacent to the angle formed by the inclined front end 2 and the bodyportion of the plow-beam with a transverse perforation, through whichpasses a pivot-bolt, and the latter adj ustably secures a clevis 4 tothe plow-beam and enables the plow to be arranged for running eitherdeep or shallow. Although the clevis is shown in the accompanyingdrawings applied to a plow-beam having an inclined front end, yet itwill be readily understood that it is equally applicable to plowshavingstraight plow-beams.

The clevis 4, which is substantially U- shaped, has parallel sideportions 5, which present fiat inner and outer faces and which areprovided at intervals with perforations 6 for the reception of thetransversepivot-bolt 3, and the front portion of the clevis is slightlythe lug 9 and'adapted to permit the same to 1 pass through them. Theplow-beam is also provided at one side of the bore or opening with abolt with a groove registering with the notches 10 and forming a passagefor the lug. After the transverse pivot pin or bolt is passed throughthe registering openings of the clevis and the plow-beam it is rotatedto carry'the lug away from the notches or recesses, whereby the pin orpivot will be securely held in place, and there is noliability of itaccidentally working or creeping out of engagement with the beam and theclevis.

The clevis is adapted to receive the pivot bolt or pin in any of itsperforations or openings, and when it is desired to lower the point ofthe plow in the ground to cause the plow to run deeper the pin isremoved and replaced in one of the perforations or-openings lying abovethe point it previously occupied, and when it is desired to raise theplow-point and cause the plow to run less deep the pin is adjusted inone ot the lower perforations or openings. By this construction the plowcan be readily adj usted to run at the'proper depth. It will be seenthat the dcviceis exceedingly simple and inexpensive in construction,that it is adapted to be readily applied to a plowbeam, and that whileit cooperates with the upturned end ot the same to raise and lower theplow-point it isbqually applicable to plows having straight plow-beams.The pivot pin or bolt is securely in terlocked with the clevis, so thatthere is no liability of it becoming accidentally disengaged, and itwill permit the position of the clevis to be readily changed.

Changes in the form, proportion, size, and the minor details ofconstruction within the scope of the appended claims may be resorted towithout departing from the spirit or sacrieing any of the advantages ofthis invention.

What is claimed is IOO I. In a device of the class described, thecombination with a plow-beam, and a pivot mounted thereon, of asubstantially U -shaped clevis having its sides adjustably mounted onIthe said pivot and adapted to be raised and lowered, whereby the lowerend of the clevis is adapted to bear againstdifferent portions ofthelower edge of theplow-beam, substantially as and for the purposedescribed.

2. In a device of the class described, the combination with a plow-beam,of a substantially U-shaped clevis provided at opposite sides withperforations arranged at intervals, and an adjustable pivot passingthrough the plow-beam and adapted to engage the said perforations,substantially as described.
